Wow––my island is also named Atlantis, and I even use the same custom path! I have Ankha and Elvis as my villagers, too~
My dream address is saved at nighttime as well. (Did you possibly get inspiration from my island before completing yours?
I'm mainly kidding lol)
I love the large star-gazing area.
The marketplace all around Able's, Nook's, and the museum is really cute and goes well with the colors of the custom path. I also like how you water-scaped your rivers and waterfalls to be relatively simple, yet consistent in width; they look very nice in the way they literally surround Resident Services and the villagers' neighborhood. Overall, a pleasantly simple and very pretty island~
Edit: I forgot to visit your house, so I went back to check it out, and it's soo cute and pretty!!
